Problems solved by technology

[0006] Of course, in practical applications, other configuration protocols such as SNMP and CLI can also perform locking operations on the network element database. Similarly, once SNMP or CLI performs a locking operation on the network element database, only the SDN controller that performs the locking operation The locked NE database can be modified through the SNMP session or CLI session that performs the locking operation. Other SDN controllers and other configuration protocols cannot make any modifications to the locked NE database.
But in this way, a configuration protocol or a configuration protocol session may lock a network element database for a long time, affecting the operating efficiency of the entire network
[0007] Although, the SDN controller wants to lock the network element database that has been locked by other configuration protocol sessions, it can force close the session by executing action to forcibly close the configuration protocol session that has locked the NEDB before performing a lock on the NEDB Operation, but in this way, the configuration protocol session that is forcibly closed will be completely cleared, and the session needs to be re-established next time, which not only wastes the time of establishing the session, increases network overhead, but also risks losing instructions and data

Embodiment 1

[0112] This embodiment is a scheduling method for locking the operation configuration database of a network element. In this embodiment, each configuration protocol session executes the NETCONF protocol and belongs to the same type of configuration protocol session. Therefore, the network element only needs to operate according to the target of each controller Priority determines the operation priority. For the sake of brevity, the operation priority is referred to as priority for short.

Embodiment 2

[0130] This embodiment is a scheduling method for locking candidate configuration databases of network elements. In this embodiment, the configuration protocol sessions executed by the controller 4 are of different types; Configure the operational priority for protocol sessions. For the sake of brevity, the operation priority is referred to as priority for short.

Abstract

The invention discloses a scheduling method and device for operating a network element database. The method includes: obtaining the type of each configuration protocol session for operating the network element database and the target operation priority of each configuration protocol session; Type and the target operation priority of each configuration protocol session, determine the operation priority of each configuration protocol session according to the preset determination strategy; when the configuration protocol session applies for operating the network element database, according to the state of the network element database and The application time point or operation priority of each configuration protocol session schedules the operation of each configuration protocol session.

Description

technical field [0001] The present invention relates to software defined network (SDN, Software Defined Network) technology, in particular to a scheduling method and device for operating a network element database. Background technique [0002] SDN is a new network architecture proposed by Stanford University in the United States. SDN realizes flexible control of network traffic by separating the control plane of network equipment from the data plane, and provides a good platform for network innovation. [0003] Among them, the SDN controller (SDN Controller) can realize the configuration and control of the network element at the same time, and the SDN controller including the configuration application (Configuration Application) communicates with the network element (Network Element) at the opposite end of the session through the configuration protocol session (Configuration Protocol Session) to configure. [0004] In SDN, Network Configuration Protocol (NETCONF Protocol, ...
